Is your Internet connection slowing down at certain times? This could be blamed on someone ( pesky neighbor who never returned your lawn rake?) using your connection with out you knowing.
A new device, in the form of semi fashionable wallpaper can block unwanted WiFi piggy packing.
Researchers at the Institut Polytechnique de Grenoble (INP) have been working on the new paper that successfully blocks out certain electromagnetic wave frequencies, which means your Wi-Fi will be secure, but your mobile signal won’t be affected at all.
The wallpaper isn’t available quite yet, but check out Ahlstrom.com for more information about how the clever tech works. Or learn to employ encryption /user passwords on your WiFi service. And demand your lawn rake back.
